转变政府职能与缓解收入分配失衡

目前导致我国居民收入分配失衡的主要是市场化改革和制度性缺陷两个方面的因素。无论从哪方面看。政府在收入分配中的缺位和错位，是导致现阶段收入分配失衡的主要原因。因此解决收入分配失衡的关键是转变政府职能，即通过规范收入分配秩序、提供公共服务、加快税制改革和财政支出改革等多种渠道发挥政府在收入分配中不同层面的调解作用，实现共同富裕。     

英文影视的大学英语教学功能

大学英语教学正不断改进教学手段,优化教学内容,提高课堂效率。论文基于学习动机理论和建构主义对教学的指导作用,分析了英文影视在大学英语教学中的优势与功能,即激发学生的学习兴趣,提高学习效率;为学生提供真实的语言环境,有助于语言的掌握;提高学生的听说技能;增强学生对文化背景的掌握,提高学生的人文素养;增多课堂互动环节,培养自主学习能力。英文影视作为一种现代教学手段,应该被积极地引入到大学英语课堂之中。     

春秋金文量词考析

在对出土古文字的研究中,历来都是文字字形的研究重于相应词汇的研究。基于《春秋金文语料数据库》,在对现有春秋金文(可识部分)进行穷尽性的调查之后,离析出其中的量词,就其使用状况加以全面观照,并进行分类分析,归纳出其语法功能与语义特征,以显示量词这一词类在春秋时期的发展脉络,以及在先秦出土文字词汇发展中的重要地位。     

论中国现当代艺术功能的单纯化——三十年代“决澜社”的艺术活动及其影响

中国现代在引入西方艺术过程中,“写实”之风强劲,原因是写实艺术在具有审美功能之外,更易体现与当时国情相适的功能(救亡图存,宏扬革命等)。但就在“写实艺术”统治现代中国画坛时,一个少为人知,在现代画史上影响不大的“决澜社”,发出了不同的声音。他们追求“纯造型世界”,追求艺术最本质,最单纯,最超然的审美功能。当下,时过境迁,社会状况、人们的观念意识都发生了巨大变化,中国的民族性也在面向国际化,三十年代“决澜社”的艺术主张及活动,被再次提出来论述,有它的时代意义。     

衡量控制权私人收益的国际文献评论

本文评论了国际上关于衡量控制权私人收益的三种方法:价格溢价、控制权价值和控制权分布与控制权溢价相结合的方法。本文认为,价格溢价方法适应于公司股票全部流通并且实行一股一票制度,而控制权溢价方法适应于现金流量权与投票权分离的公司制度。控制权分布与控制权溢价结合的方法更具有一般性,适合于衡量现金流量权与投票权分离或一致两种情况下的私人收益。     

Approximate optimal allocation in repeated sampling from a finite population

Samples of size n are drawn from a finite population on each of two occasions. On the first occasion a variate x is measured, and on the second a variate y. In estimating the population mean of y, the variance of the best linear unbiased combination of means for matched and unmatched samples is itself minimized, with respect to the sampling design on the second occasion, by a certain degree of matching. This optimal allocation depends on the population correlation coefficient, which previous authors have assumed known. We estimate the correlation from an initial matched sample, then an approximately optimal allocation is completed and an estimator formed which, under a bivariate normal superpopulation model, has model expected mean square error equal, apart from an error of order n^-2, to the minimum enjoyed by any linear, unbiased estimator.

Censored Kullback-Leibler Information and Goodness-of-Fit Test with Type II Censored Data

The Kulback-Leibler information has been considered for establishing goodness-of-fit test statistics, which have been shown to perform very well (Arizono & Ohta, 1989; Ebrahimi et al., 1992, etc). In this paper, we propose censored Kullback-Leibler information to generalize the discussion of the Kullback-Leibler information to the censored case. Then we establish a goodness-of-fit test statistic based on the censored Kullback-Leibler information with the type 2 censored data, and compare the test statistics with some existing test statistics for the exponential and normal distributions.     

论网络外部性下移动通信技术的选择

通过对网络外部性理论进行分析，对网络外部性（Network externality）以及梅特卡夫定律（Metcalfe’s law）简述，在Katz、Shapiro等学者对网络外部性研究的基础之上引入效用函数，并着重以移动通信技术的选择为例，以效用函数为核心建立简单的数学模型，从消费者、运营商、政府三个方面综合分析，最终近似得出移动通信技术选择的可行性区域，旨在为我国移动通信业的持续发展，提供一种思维角度和方法。     

On Bayesian estimators in multistage binomial designs

A new class of Bayesian estimators for a proportion in multistage binomial designs is considered. Priors belong to the beta-J distribution family, which is derived from the Fisher information associated with the design. The transposition of the beta parameters of the Haldane and the uniform priors in fixed binomial experiments into the beta-J distribution yields bias-corrected versions of these priors in multistage designs. We show that the estimator of the posterior mean based on the corrected Haldane prior and the estimator of the posterior mode based on the corrected uniform prior have good frequentist properties. An easy-to-use approximation of the estimator of the posterior mode is provided. The new Bayesian estimators are compared to Whitehead's and the uniformly minimum variance estimators through several multistage designs. Last, the bias of the estimator of the posterior mode is derived for a particular case.
